Joint for wall panels made of cross laminated timber

A wall panel joint assembly comprising:

• at least two adjacent wall panels with a joint therebetween when the panels are connected to one another, each of the wall panels comprises a front face and a back face, spaced apart from the front face (3), two side edges (5), where each of the side edges extends between the front face and the back face on each respective side of the faces, and a top edge (6) and a bottom edge (7);
• wherein each of the side edges comprises a protrusion extending therefrom and a groove adjacent to the protrusion, wherein at the end of the protrusion a heel is formed so that upon interconnection of the two adjacent wall panels the heel of one of the wall panels is inserted into the groove of the adjacent wall panel and the interconnected wall panels form a wedge space therebetween defined by the heels and protrusions of the interconnected wall panels,
• wherein the wall panel joint assembly further comprises a set of two wedges, wherein each of the wedges is an elongated bar and comprises opposite wedge side edges, one of the wedge side edges is inclined with respect to the other of the wedge side edges, the inclined edges of the wedges are opposed to each other and configured to be inserted into the wedge space forming an interference fit between the wedges and the wall panels;
• and
• wherein each of the wall panels is made of cross laminated timber (CLT).
